Desperately seeking info re: J.E. Alexander of Grayson Co. TX

J.E. Alexander was my Great-Great Grandfather. I believe his first name was James & he went by "Jim." He was born about 1863 and died in 1899. He married my Great-Great Grandmother, Sarah "Sallie" Dishman on 10/18/1891 in Grayson Co. TX and had 2 children, my Great-Grandmother Vesper Sarah Alexander (born 4/3/1893) and a son (name unknown). I believe he is buried in Dixie Cemetery in Dixie Community, Grayson Co. TX. Other than this, I know no other information about him. ANY shread of info (actual birth/death date, parents names, ect.) anyone may have would be invaluable to me. If you can help, PLEASE contact me! Thanks!
